When you're new, A LOT of assholes will contact you. Fake sugar daddies, last-minute seekers, hagglers, people wanting half hours, etc. It WILL pass. Or, it won't exactly pass (they'll always try but in fewer numbers once you're no longer new) but later on, the idiots will be outnumbered later by the nice clients.
My advice is just to hang in there. When you want to start off on the right foot, it WILL take a little bit of time before the money starts to come. But, it's better to start the right way and not take shortcuts, than to take shortcuts and be sorry later.
If you won't take same day appointments, realize that the reviews will come more slowly. The majority of reviews are written about 1-hour incall appointments and a lot of people who want 1 hour incall also want same-day. But, I'm assuming that you want quality over quantity...so just have faith that it will pay off in the end

Imagine if you compromise on this, and someone reviews you like: 'I was super horny and asked this girl if she could be available in an hour. Since she said yes I went for it even though I was in the mood for a blonde. I just wanted a BJ and a quick fuck so I asked her to get undressed...etc, etc.' Ick.
When you want quality...it takes time and patience to build your business
